‘Human challenge trials will help us design better treatments, vaccines than we can now’

R. Prasad In January, London will begin the world’s first human challenge trial, the Financial Times reported. The trial will be run by hVivo, a spinout from Queen Mary University of London that was bought earlier this year by a Dublin-based pharmaceutical research organisation, while Imperial College London is the academic partner. Participants will be vaccinated with a candidate vaccine and then wilfully exposed to novel coronavirus (SARS-CoV-2) a month or so later. Over 38,000 people from 166 countries
